3D-printed batteries could replace traditional cells in the near future

We’ve seen 3D printing technology lead to a number of breakthroughs but the latest could be the most viable and important yet. Harvard materials scientist Jennifer Lewis has been using new tools and inks to create 3D printed batteries and...

Don't get me wrong, being able to cram a tiny battery in small places is great for things already small like [smart] watches, HUD devices like google glass, and the like, but that's not my personal priority.

But remember, the smaller a battery is, the more we can cram in tight places meaning multiple batteries on one source. Battery tech is a slow evolving technology that is getting difficult with power consumption going up to keep up with. If we are able to cram lots of little batteries in tight places with good life, we can make things last longer just based on that.

This could lead to even smaller tech gadgets like smartphones and tablets, among other things.

Naturally they jump to decrease the size of the battery instead of increasing run time longevity. I'm sick of the consumer/industry wanting smaller and smaller devices, while we fall into a daily ritual of making sure our devices are charging. Why even have a portable device, if we are going to have daily maintenance charging it.
